There are a lot of use cases why customers build their own container images.
Two examples are platform teams that provide a set of base-images as a service for the developer teams or the developer teams themselves that use this images to add their runtime and app.
Often this is done through central build pipelines that use docker build hosts, which then for example use "docker in docker" to build the images.
Even if this works pretty well, there are some drawbacks, for example the scaling of this build hosts, but especially the fact that every build is actually run with privileged permissions, which can cause handling and security issues.
In this talk we will have a look at:
– the possibilities to build container images in an unprivileged OpenShift environment
– tooling around this
– scaling the build environment and also
– be able to scan / analyze the content of the image and store the report to fulfil compliance needs
